Observation of exciton redshift-blueshift crossover in monolayer WS2
Edbert J. Sie, Alexander Steinhoff, Christopher Gies +10
We report a rare atom-like interaction between excitons in monolayer WS2, measured using ultrafast absorption spectroscopy. At increasing excitation density, the exciton resonance…
Large, valley-exclusive Bloch-Siegert shift in monolayer WS2
Edbert J. Sie, Chun Hung Lui, Yi-Hsien Lee +3
Coherent light-matter interaction can be used to manipulate the energy levels of atoms, molecules and solids. When light with frequency ω is detuned away from a resonance ωo, repul…
Observation of intervalley biexcitonic optical Stark effect in monolayer WS2
Edbert J. Sie, Chun Hung Lui, Yi-Hsien Lee +2
Coherent optical dressing of quantum materials offers technological advantages to control their electronic properties, such as the electronic valley degree of freedom in monolayer…
